M: mother; I: infant. ^aLength of infection: The closest time of infection that we could document was the first positive HIV-1 serology date or the first visit of the patient to the AIDS treatment Center, where all the HIV-1 positive patients were referred to as soon as an HIV-1 test was positive. Therefore, these dates may not reflect the exact dates of infection. ^bEvaluation for infants is based on CDC criteria, ^cddC, Zalcitibine
